CLOCK.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed August 10,1906. Serial No. 329,997.

To all whom it may concern:

Be it known that I, Aensrrn SUAREZ PEREDO, a citizen of the Republic of Mexico, and a resident of Coatepec, in the State of Vera Cruz, Mexico, have in- 5 vented a new and useful Improvement in Clocks, of

which the following is a full, clear, and exact description.

The purpose of the invention is to provide a striking attachment to clocks, particularly alarm or striking clocks, which will be independent of the customary alarm or striking mechanism, whereby to provide for a single stroke of a bell, gong or its equivalent at any desired interval, as for instance every five, ten, fifteen, twenty, thirty or sixty minutes, which auxiliary striking attachment may be silenced whenever desired and may be operated in conjunction with the ordinary alarm and striking mechanism of the clock without in any manner interfering therewith.

A further purpose of the invention is to provide an attachment of the character described which will be very simple and easy of adjustment and which can be economically applied to any clock.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a rear elevation of an alarm clock with the improvement applied, the back plate being removed and the gong being shown in section; Fig. 2 is a vertical central section through the clock, the section being taken practically on the line 2-2 of Fig. 1; Fig. 3 is an enlarged rear elevation of a portion of the clockwork removed from its casing and a rear elevation of the applied repeating attachment; Fig. 4 is a detail sectional view taken practically on the line 44 of Fig. 3; Fig. 5 is a plan view of the clock work and applied attachment and Fig. 6 is a detail perspective view of the trip fork for the auxiliary alarm. Fig. 7 is a plan view of the regulating wheel and its associated parts; Fig. 8 is a side elevation of the parts shown in Fig. 7 and Fig. 9 is a vertical section taken practically on the line 99 of Fig. 8.

A represents the casing of an alarm clock, B the customary gong mounted thereon in the usual manner, B the regular hammer for the gong B, and 0 represents --\th e framework of a clock mechanism of the ordinary 50 type provided with the usual or appropriate spring and train of gearing O.

The usual hands 10 and 11 are employed, mounted in the customary way, but at the rear end of the post 12 for the minute hand 11 what 1 term a trip wheel 13 55 is secured. This trip wheel is provided with a series of 1 pins 14 which extend out from its rear face, and said pins 14 are preferably twelve in number and are of different lengths for a purpose to be hereinafter described. Sundry of the pins 14 extend through the wheel be ,ond its forward face, and these forwardly extending Jins 15 are preferably six in number and are in two lengths, three being of one length and the other three longer. The pins 14 and 15 have pointed ends as illus trated.

An auxiliary hammer D is employed adapted to operate upon the gong B, or the equivalent thereof, and this auxiliary hammer D is carried by a stem 16. This stem is carried downward and then rearward over the top portion of the frame C of the clock work, and is socured at the rear portion of said frame C to a plate 17 which plate is provided with an eye or a sleeve 18 at its lower end, mounted to turn upon a stud 19, which extends horizontally from the upper rear portion of the frame 0 as is shown best in Figs. 3 and 1.

What may be termed an actuating mechanism E for the auxiliary hammer D, consists of a sleeve 20 mounted to turn on the sleeve 18 secured to the hammer plate, and arms 21. extend upward from the said sleeve 20, one at each side of the hammer plate 17 and from one of the upwardly-extending arms 21 parallel ears 23 are carried outward, usually in direction of one side edge of the frame 0, as is best shown in Figs. 1 and 3. From the sleeve 20, which has sliding as well as rocking movement on its support a stem 2 1 is carried downward, which terminates in a fork 24. The fork 24 straddles the trip wheel 13 as best shown in Fig. 4, and said fork 24 is movable to and from the side faces of the trip wheel 13, so as to bring the pins 14 or 15 of different lengths to an engagement with one or the other of the members of the said fork. The opposing members of the fork 21 have their inner edges beveled at each side to facilitate the withdrawal of the pins 14 and 15 therefrom, as is illustrated in Fig. 6.

A spring 25 is secured at one of its ends to the hammer stem 16 adjacent to that portion of the stem which connects with the pivotally mounted plate 17; and the opposite end of the spring is secured in any suitable or approved manner to the rear portion of the frame C for the movement as is clearly shown in Figs. 1, 3 and 5; and the hammer operating or actuating member 24 of said hammer actuating mechanism E is held normally in the vertcial position shown in Fig. 3 adjacent to a pin on the trip wheel 13 by engagement with a-spring stop 26; and when the hammer operating member 24 is pressed outward to operate the hammer by the rotation of the wheel 18 as indicated in Fig. 1, said member 24 is moved away from said stop and the auxiliary hammer D is drawn back and the spring 25 is placed under tension. The moment that the hammer operating mechanism 24 is relieved from engagement with its engaging pin 14 or 15 the spring 25 draws the hammer back and causes it to contact with the gong B and thus sound an alarm.

The hammer actuating mechanism E acts in con junction with a time regulating mechanism which is as follows: The ears 23 forming a portion of the hammer actuating mechanism E receive between them a plate 27, which plate is secured to the vertical member of an angle or elbow arm 28, the horizontal member of which arm is provided with a slot 28 as shown in Fig 1-, for the downward passage of the stem or shank 24. of the hammer operating member 24; and this bifurcated member of the arm 28 serves as a guide for the hammer operating member in its movement to and from the pins on the wheel 13, and since the upper portion of the arm 28 is secured to the outer end of a rack 29 mounted to slide on the top of the frame 0 between suitable bearings 30, as said rack is moved inward or outward the angle or elbow arm 28 is correspondingly moved and carries With it the hammer operating member 24, enabling said hammer operating member 24 to act in conjunction with the trip wheel 13 whether the said member is moved forward close to the frame or outward therefrom.

The rack 29 is operated through the medium of a pinion 31, and this pinion is secured to a shaft 32 mounted to turn in suitable bearings on the upper portion of the frame 0 as is particularly shown in Fig. 5, and said shaft 32 passes out through a suitable opening in the casing A and terminates in a knob 33 or its equivalent. A. dial wheel 34 is secured on the said shaft 32, and this dial wheel is preferably in the form of the frustum of a cone, and the figures thereon are readable through an opening suitably produced in the casing A at a point above the shaft 32.

The pins 14 at the rear of the trip wheel 13 serve for producing a stroke at intervals of five, fifteen, thirty and sixty minutes; and the pins 15 at the inner or front face of said wheel 13 serve for producing strokes at intervals of ten and twenty minutes. The figures on the dial wheel 34 read 0; 60, 30; 15; 5; and as one or the other of these figures appear at the said opening in the casing, or are brought uppermost by turning the knob and consequently the dial wheel 34, the hammer operating mechanism 24 of the actuating mechanism E is cl'rrrespoiulingly shifted to or from the rear face of the trip wheel 13 to be engaged by a longer or shorter pin on the wheel 13 since said wheel is revolved by the clock work mechanism so as to influence the hammer D to strike the gong B at the set intervals.

The figures 10 and 20 are produced upon the dial wheel 34 between the cipher thereon and the figure 5; and these figures 10 and 20 relate to the pins 15 on the front of the trip wheel 13, and in setting them the hammer operating member 24 is moved the proper distance to and from the said front face of said wheel 13 to be engaged by either one or the other set of pins thereon.

\Vh en the hammer operating member 24 is set to act relatively to the pins 1-i the said member is free from the pins 15, and the reverse is also true; and when the cipher on the dial wheel 3 f is uppermost or exposed, the hammer actuating member 24 will occupy such a position as to be out of the path of all of the pins 14 and 15.

The longest of the pins 14 is for causing a stroke to be sounded at intervals of sixty minutes; consequently it comes in contact with the hammer operating member 2-1 once only each hour; and the same pin and a shorter one diagonally opposite act for the gong to be struck at intervals of thirty minutes. These two pins 1i and two others of lesser length are brought into action for the gong to be struck at intervals of fifteen minutes, and all of said pins are available for causing a stroke at intervals of five lninutes.

With reference to the pins 15 and the trip wheel 13, the three first pins 15 are the longest and operate for time intervals of twenty minutes, and the full set of of said pins 15 is brought into service when. an alarm is to be sounded at intervals of ten minutes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent,

In a striking attachment to clocks, rmrticularly alarm or striking clocks. the combination with the clock movement and a gong, of an auxiliary striking mechanism independent of the customary alarm or striking mechanism and consisting of. a spring-controlled hammer with the gong. a rocking support therefor, a striking wheel mounted upon the minute hand post of the movement and provided with a series of pins of varying length extending from opposite sides of the wheel, one series of pins being operative. for time intervals of a designated length, the other set of pins operating for time intervals of a different: duration, an operating member for the hammer having sliding and rocking relation to the hammer support, said operating member having a section bifurcated to straddle the trip wheel. said bifurcated section being adapted to be brought into the path of either series of pins on said wheel, and means for carrying the operating member to and from the sides oi the trip wheel and to and froin the path of certain oi its pins.

2. in a clock, the combination with the movement. thereof. an alarm device, a tension controlled hammer for the alarm device, and a rocking support for the said hummer. of :1 trip \vheel secured upon the minute hand post of the movement, projections ot. varviug length carried by the said trip wheel, which projections are at stated intervals apart, an operating member for the said hammer, having sliding and rocking relation to the hammer support, the said operating member having a section bifurcated to l raddle the trip wheel, a rack and pinion adjusting mechanism for the said operating member, whereby to carry it to predetermined relation relatively to the projections from the lid trip wheel, and a dial wheel included in the said adju 1g mechanism for the purpose described.

In to nuony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
